(color online) (a) Low-resolution TEM image and (b) the corresponding SADP patters of 1T-TaS₂ along [0001] projection uncover the evident 6-fold rotational symmetry. (c) Atom-resolved HAADF and (d) ABF STEM images seen from [0001] projection (c axis). Brighter spots represent Ta atomic columns (larger orange circles), while darker ones S atomic columns (smaller green circles).
